How to use 6N1P and 6N2P Russian tube
6N1P and 6N2P are the most popular small signal twin triodes
in Russian audio. Download datasheet for this tubes here.
They was thought as 9 pin replacements for octal 6H8C (6SN7
GT) and 6H9C (6SL7 GT) respectively. Both have built - in shield. Great tubes
with great sound.
In the following notes a number of typical circuits in which
both 6N1P and 6N2P can be employed as amplifier and fase inverter are described.
Pic. 1 shows standard line stage amplifier. You can obtain
aprox. 9V (12V for 6N2P) output with THD less than 0,1%. Aprox. gain will be
20 - 25 (50 for 6N2P).
Pic. 2, pic. 3 and pic. 4 show standard
fase inverters. Aprox gain is 60 for pic. 2 and 30 for pic. 3.
